APPARATUS FOR WAXING PAPER, 800.

SPECIFICATION forming part of Letters Patent No. 345,864, dated July 20,186.

Application filed April 15, 1886.

Serial No. 19:298.. (No model.)

' hereby declare the following to be a full,clear,

and exact description of the invention, such as will enable othersskilled in the art to which it appcrtains to make and use the same.

Our invention relates to an improvement in apparatus for waxing paper orother material.

The object is to provide means for coating to a greater or lesserthickness, or partially or completely saturating paper or othermaterial,with wax, paraffine, and the like, by the capillary process,and to further provide a simple, effective, and economical apparatus forthe above purpose.

WVith these ends in view our invention con sists in certain features ofconstruction and combinations of parts, as will be hereinafter describedand pointed out in the claims.

The accompanying drawing represents the apparatus in verticallongitudinal section.

A represents a tank in which the wax, paraffine, &c., is kept in aliquid state by heat from a series of steam-radiator pipes, 13, or byany other suitable means. From the tank A a pipe, (0, leads to a well,0, situated as low or lower than the tank A, in order to cause themelted wax to flow freely from the tank thereto. The pipe a is providedwith a stopcock, a, to regulate the flow of the melted wax. Over thewell 0 is a porous slab or series of slabs, D,of stone, wood, or othersuitable matcrial,kept at the desired temperature by a series ofradiator-pipes, b, which may conveniently be a continuation of the pipesD,or may be a separate series. Through a slot in the slab D, or throughan opening between two of the slabs D, a bunch of wicking, felt, orother fibrous or porous material,E,adapted to raise the wax by capillaryattractiomis located and preferably surrounded by a tube, 6. The latteris adapted to be raised and lowered by a pinion, f, on a rotary shaft,E, which meshes with a series of teeth or notches, f, on the tube. At ashort distance from the tube 0 there is a second opening in the slabD,or between the slabs, through which a second bunch or block ofwicking, felt, or the like, E, projects. The lower end of the wicking Edoes not, however, extend to the surface of the melted wax in the well,and is employed as a V return-conduit, as will hereinafter appear.

G represents the paper. It is drawn from a reel, H, over a pair ofrollers, I, and be neath a pressureroller, 13. The rollers I aresynchronously geared,and the roller 1' is driven by its frictionalcontact with the roller I, and the tension of the paper is regulatedthereby. From the rollers I i the paper extends up and -over the face orfaces of the slab or slabs D,

over the top of the wicking E, and thence along the face or faces of theslab or slabs D, over the top of the wicking E; thence to the set ofrollers K insimilar to and geared in the same manner as the rollers I i;thence into the receptacle L, and thence through a set of rollers, M m,to the cutter N.

The cutter or cutters N consist, essentially, of a drop-knife or rotarycutter or cutters operated by a wheel, 0, geared with the rollers M m,which,by a series of cams or other equivalent means, alternately engageand release a lever, 1?, attached to the drop-knife.

The paper as it passes over the slabs is kept heated by heat from theslabs, and is hottest on the side which is to receive the wax. As itpasses over the top of the wicking E it is covered with wax drawn upfrom the well 0 by the wicking, felt, &c. As it passes along over theslabs after leaving the wicking E any superfluous wax is removed by thesecond set of wicking, E, the wax being returned through said wickinginto the well.

The pressure of the wicking in the tube 6 is regulated by raising orlowering the tube,and the waxed surface may be operated upon by two ormore bunches of wicks or felt, E, instead of one. The same arrangementmight also be employed above the paper for coating the upper side aswell as the lower.

e are aware that it is not new to pass the paper on a felt block thelower end of which is immersed in a tank containing the wax. \Ve arealso aware that it is old to provide a paper-waxing machine with one ormore wicksupports and one or more guides, the parts being arranged sothat the paper rubs over the side of the wick, and hence we make noclaim to such construction.

It is evident that slight changes might beresorted to in the form andarrangement of the several parts described without departing from thespirit and scope of our invention hence we do not wish to limitourselves strictly to the construction herein set forth but,

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-

1. In apparatus for waxing paper, the combination,with a porous slab orslabs over which the paper is drawn, of a bunch of capillary tubesleading from a reservoir beneath the said porous slab or slabs upthrough the same into contact with the paper, substantially as setforth.

2. In apparatus for waxing paper, the combination,with a porous slab orslabs and means for keeping them at the desired temperature, of avertically-adjusliable bunch of capillary tubes leading from a wellbeneath the slab or slabs to a point above their uppersurface,substantially as set forth.

3. In apparatus for waxing paper, the combination, with a porous slab orslabs and ineans for heating the same, of a bunch of felt or othersuitable material adapted to feed the wax up through an opening in theslab,or between the slabs, and a bunch of capillary tubes adapted toconvey the superfluous wax down through an opening in the slab or slabs,substantially as set forth.

4. In apparatus for waxing paper, the combination,with one or more slabsof porous materialsueh as soapstone, pumice stone, and the likeand meansfor passing paper over their surface, of a bunch of capillary tubesinclosed within a casing, and a pinion and series of notches foradjusting the casing, and hence the capillary tubes, substantially asset forth.

5. The combination,with the tank of melted 0 wax, the well located aslow or lower than the tank, and a pipeleading from the tank to the welland provided with a stop-cock, of the porous slab or slabs located overthe well, the bunch of capillary tubes leading from the well 5 throughthe slab or slabs, and the several sets of rollers adapted to regulatethe movement of the paper over the slab or slabs, substantially as setforth.

6. In an apparatus for waxing paper, the combination, with a porous slabor slabs over which the paper is drawn,and a bunch of cap illary tubesleading from the reservoir beneath the said porous slabs up through thesame into contact with the paper, and rollers for feeding the paper, ofthe cutter or cut ters located and operated substantially as set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
